My 2014 LR4, with 80,000 miles has at least 1 right front control arm bushing. (I think, haven't had on lift yet. Clunks when braking and speed bumps, in right front. Steering shakes at most speeds, braking or not. I have seen many options from replacing entire control arms to just bushings and many different bushings. 1. Is this normal at 80k miles? I dont off road much, but occasionally tow a 4k lb trailer 2. Should i replace all bushings, upper, lower, left and right front, even if others seem tight (my gut says yes) 3. Anyone here done it? How difficult in a modestly equipped shop, high jack stands, most tools hand and pneumatic? 4. I have a 5 ton press and some various mandrels, but is the the aggravation and time to replace bushings worth tge cist savings, which are substantial? Or better to just replace to whole arm assemblies? I appreciate and experienced advice. I dont turn wrenches any more for years, but the dealer here is always a dissappointment.
